Allen-Bradley 2707-L40P2 – DTAM Plus Operator Panel | DTAM Plus Series
Engineering Background
The Allen-Bradley 2707-L40P2 is part of Rockwell Automation’s DTAM Plus (Display Terminal And Manager) series — a compact, panel-mount operator interface designed for direct integration with Allen-Bradley PLC platforms including SLC 500, MicroLogix, and PLC-5 families. Engineered for industrial environments where space is constrained but operator visibility and control are non-negotiable, the DTAM Plus bridges the gap between basic pushbutton stations and full-featured HMI touchscreens.
Product Positioning
The 2707-L40P2 is the preferred choice for OEM machine builders and system integrators requiring a cost-effective, DIN-rail or panel-mount operator terminal with native Allen-Bradley communication. It delivers reliable alphanumeric display, programmable function keys, and direct DH-485 network connectivity — making it ideal for retrofit projects, standalone machine control, and distributed I/O monitoring applications where a full SCADA or touchscreen HMI is over-specified.

System Architecture & Signal Flow
The 2707-L40P2 connects directly to the DH-485 port of an Allen-Bradley SLC 500 or MicroLogix PLC via a standard 1747-C13 or equivalent cable. The DTAM Plus acts as a network node (slave device), polling the PLC’s data table for display values and writing operator inputs back to designated integer or bit files. Application screens, messages, and function key assignments are programmed offline using the DTAM Plus Programming Software and downloaded via the same DH-485 port or a dedicated programming cable. In multi-node configurations, a single PLC can serve multiple DTAM Plus terminals, each assigned a unique node address (1–31).
Typical Signal Flow: Operator Input (Keypad) → DTAM Plus CPU → DH-485 Network → SLC/MicroLogix Data Table → PLC Logic Execution → Output Update → DTAM Plus Display Refresh

Technical FAQ
Q: Is the 2707-L40P2 compatible with CompactLogix or ControlLogix PLCs?
A: No. The DTAM Plus uses DH-485 protocol, which is native to SLC 500 and MicroLogix platforms. CompactLogix and ControlLogix use EtherNet/IP or DH+. A protocol gateway (e.g., ProSoft MVI56-DFNT) would be required for integration with Logix5000 platforms.
Q: Can the DTAM Plus display real-time analog values?
A: Yes. The DTAM Plus can read and display integer and floating-point values from PLC data files, including scaled analog inputs, enabling real-time process variable monitoring.
Q: What programming software is required?
A: Rockwell Automation’s DTAM Plus Programming Software (Cat. No. 2707-NP1) running on a Windows PC. Legacy versions are compatible with Windows XP through Windows 10 with appropriate compatibility settings.
Q: Is the unit available with a warranty?
A: Yes. All units sold through Konmask.com carry a 12-month operational warranty. Extended warranty options are available upon request.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. For out-of-stock inquiries, lead time is quoted individually based on sourcing availability.
